Download Huawei Enterprise Simulation Platform eNSP

As you probably know, the eNSP, for some and other reason, is not supported anymore and disappeared from Huawei’s website.

But I do have it, so if you need to download it, you get a saved version from me.

The shared package contains all the necessary components for the NSP to work properly.

So feel free to download the working version of Huawei Enterprise Simulation Platform.

Once you have eNSP installed, there is nothing stopping you from using it, by purchasing my HCIA course on Udemy, which you can find now at a promotional price until December 13th.

Destination NAT on Huawei USG firewall

If you have an FTP server or any other server that you want to make available to internet users, just place the server in DMZ zone of your firewall e.g. Huawei USG and configure a destination NAT. You can then easly restrict IP addresses and protocols that can access your server. And this video is just about that 😉

USG firewall configuration script:

#
interface GigabitEthernet1/0/1
undo shutdown
ip address 10.0.100.1 255.255.255.252
#
interface GigabitEthernet1/0/2
undo shutdown
ip address 5.0.0.2 255.255.255.252
#
firewall zone untrust
set priority 5
add interface GigabitEthernet1/0/2
#

#

PAT or no-PAT – source NAT on Huawei USG6000

If you, for some reason, cannot use easy-ip NAT, you can use source NAT with NAT address pool. Depending on how many public IP addresses you have got, you can configure no-PAT option, when only IP address is translated or you can set PAT, in other words NAT with port translation to assure LAN users accessing Internet. Details in the video 😉

USG firewall configuration script:

#
dhcp enable
#

Easy-IP source NAT on Huawei USG firewall

A short video describing EASY-IP source NAT on Huawei’s USG firewall to assure that our intranet users can acccess the Internet.

The easy-ip is the easiest way to translate private IP addresses on your local area network when you have only one public IP address or the public IP address is assigned dynamically.

USG firewall configuration script:

#
dhcp enable
#
interface GigabitEthernet1/0/0
undo shutdown
ip address 10.0.0.1 255.255.255.0
service-manage ping permit
dhcp select interface
dhcp server excluded-ip-address 10.0.0.100
dhcp server static-bind ip-address 10.0.0.200 mac-address 5489-98b4-6a79
dhcp server dns-list 10.0.0.100
#

DHCP IPv4 server on Huawei USG6000 firewall

You know how to configure DHCP on Huawei router but have problem to do so on Huawei firewall? Take a few minutes and see how to do that.

DHCP IPv4 server that uses interface’s address pool to allocate IPv4 addresses to DHCP clients. The simplest way to implement DHCP on USG6000.

USG firewall configuration script:

#
dhcp enable
#
interface GigabitEthernet1/0/0
undo shutdown
ip address 10.0.0.1 255.255.255.0
